\nBy combining green and red colours of light, the colour yellow is obtained.
\n<\/section>\n
\nThis refers to additive colour mixing, which is relevant for light. The primary colours of light are Red, Green, and Blue (RGB). When these primary colours are mixed in different proportions, they produce other colours. Combining two primary colours results in a secondary colour: Red + Green = Yellow, Red + Blue = Magenta, Green + Blue = Cyan.
